Yorick-based adaptive optics system simulator

Yao is a monte-carlo simulation package for adaptive optics. It can
be used stand-alone through a GTK-based integrated graphical user
interface or as a Yorick language extension. Yao features:

* Shack-Hartmann and Curvature WFS, on or off axis;
* support for Stackarray (piezostack), curvature (bimorph), modal
(zernike) and Tip-Tilt deformable mirrors. The altitude of
conjugation is adjustable;
* arbitrary number of WFSs and DMs, with the possibility of mixing
types. It is therefore possible (and easy) to simulate single DM
systems, as well as single non-zero conjugate, GLAO and MCAO
systems;
* support for Natural and Laser Guide Stars (or a mix), WFS with
photon and read-out noise;
* multi-layered atmospheric model with geometrical propagation
only;
* speed-optimized loop: critical routines have been coded in C.
